Adrian Bell, Chris Brooks∗ and Tom Markham ICMA Centre, University of Reading, Whiteknights, PO Box 242, Reading RG6 6BA, UK This paper develops a performance management tool and considers its application to the foot- ball industry. Specifically, the resulting model evaluates the extent to which the performance of English Premier League football club managers can be attributed to skill or luck when mea- sured separately from the characteristics of the team. We first use a specification that models managerial skill as a fixed effect and we then implement a bootstrapping approach to gener- ate a simulated distribution of average points that could have taken place after the impact of the manager has been removed. The findings suggest that there are a considerable number of highly skilled managers but also several who perform below expectations. The paper proceeds to illustrate how the approach adopted could be used to determine the optimal time for a club to part company with its manager. I. Introduction control costs. The outlay on player registrations (transfers), player wages and stadia development are the principal foundations for this. Motivated by the much larger literature on the identification of Another prevalent cost for professional football clubs is the hiring mutual fund manager skill, this paper proposes the adoption of a and firing of management teams.Acquiring the right manager is inte- bootstrapping methodology to evaluate the performance of football gral to a club’s on-field success (Brady et al., 2008).

Throughout the paper, we use the term ‘football’ rather than ‘soccer’. 2 We have used the terms ‘sacking’ and ‘firing’ interchangeably throughout the paper as both are used in common parlance internationally to mean immediate dismissal from a job. © 2013 Adrian Bell, Chris Brooks and Tom Markham 20 A.
